This invention relates to a paper or .cardboard carton of the compartment type comvmonly called an egg carton and adaptable to the packagin of other fragile articles.

The chief o ject of the invention is to form an egg carton which has greater crushing strength by reason of the method of construction over similar cartons formed from the same type and weight of material and which also is adapted to retain the eggs or the like without permitting end escapement thereof and also reduce the possibility of breaking or crushing by yieldingly mounting each egg or the like in the carton.

The chief feature of the invention consists in the accomplishment of the foregoing ob- 25 sists in the formation of the egg carton or the like from a substantially rectan lar. blank suitably cut, scored andperforate and scored, the length thereof being substantially twice the width for a double and longitudi- 80 nally divisible carton, the blank being substantially square for such a single unit carton.

A further feature of the invention consists in substantially severing the rectangular blank into two square portions but having a very small portion nnsevered, said portion forming a hinge and integral connection between the two readily divisible parts of the carton.

The full nature of the invention will be understood from the accompanying draw ings and the following description and claims:

In the drawings Fig. 1 is a plan view of the substantially rectangular blank completely cut, scored and perforated and scored prior to the folding of the same into the multiple unit carton. Fig. 2 is a perspective view'of the multiple unit carton, one unit 60 thereof being closed. and the other being EGG CARTON 1928. Serial No. 276,292.

opened. Fig. 3 is an end view of the carton with an egg therein.

In the drawings 10 indicates two substantially square halves of a blank which have the aligned slots 11 and 12 and are united by a scored portion 13 (see Fig. 1). Each square forms a complete demi-carton. The two are united togetherpalong an adjacent edge by the scored portion 13 and the opposite edges indicated at 14 may be united together by a sticker 15, see Fig. 2, or may be adhesively united together in carton formation. Since the demi-cartons are substantially identical, a description of one will suifice for both.

In the blank 16 indicates the longitudinally scored hinge connection between the cover, extension or side wall cooperating portion 17 and the cover 18. 19 indicates the scoring between the cover 18 and the side wall 20,. 21 indicates the scoring between the side wall 'and the bottom 22. 23 indicates the scoring between the bottom 22 and the shorter side wall 24. 25 indicates'the scoring between linear slots 26 or arcuate slots 27 and is the connection between the side walland the sectionali'zed top. The intermediate flap or inner side wall 28 is similarly connected to the sectionalized top. The scored portion 29 connects thefiaps or inner side to the false bottom 30, transversely slotted at 31 and terminating short of the edge thereof. A positive stop to limit the outward movement of the end flaps in the form of projections 131 may be provided.

By referring particularly to Fig. 3 it will be noted that the side wall 20 connects the cover 18 and the bottom 22 together. 7 The sectionalized top 32 is connected to the u per end of the side wall 24, the lower end of w ich is connected to the bottom 22. The falseor inner side wall 28 is connected at its upper end to the top and at its lower end to the false bottom which rests upon the bottom 22 and is inclined upwardly and angularly relative thereto. As shown clearly in Fig. 3, the two false bottoms are directed upwardly and outwardly from the adjacent side walls 24 of the two parallel positioned demi-cartons. Projecting from the cover 18 is the flap 17 and .the tongues 33 thereof are adapted to be receivable by the cut-outs formed at 27. The longitudinal edge 34 bears upon the top, as shown in Fig. 3 and inward collapse of the top is prevented. This forms a compartment above and below the sectionalized top and the article is adapted to project through the sectionalized top into the upper compartment. The tongues 33 have a locking engagement as indicated. To assist in preventing lateral collapse of the side wall lock or cover extension 17, the arcuate cut-outs 27 form the upwardly extending reinforcing members 35. When the side wall locking extension 17 is positioned outside of the arcuate extensions 27 of the side wall 24, said sidewalls prevent complete collapse of the cover 18 toward the top.

The sectionalized top has formed at each end a air of flaps 36 by the arcuate cuttings 27 and the linear cuttings 26, the same being connected together by the tongue forming cuttings 37 and the flap is divided and herein by an inclined scoring as at 38 forming an angular extension 39 on said flap. As shown in Fig. 2, the end flaps 36 extend downwardly and inwardly toward the centerof the demicarton and thus provide ends for said carton and prevent end escapementof the. articles. To insure substantially complete closure of the ends of the demi-carton the angularly positioned tongues 39 register with and lie parallel to the inclined and false bottom 30. The result is that the greater the tendency of the article to escape, the greater the resistance to such escapement. The slots 31 or the top portions 131 limit the escaping or outward movement of the end forming flaps.

To provide an intermediate compartment with a suitable side cushioning support in addition to the cushion support provided by the false bottom, the top is divided by a saw tooth slot 40 which form the two inwardly directed flaps 41 having tongue portions 42, the over-all length of each flap and tongue being'greater than half of the distance of the compartment formed by two flaps and tongues. These are depressed downwardly (having the scored connection 43 with the remainder of the top) and thus form a cushion and prevent lateral escapement of the article in either direction. Each of the end flaps 36 also are folded upon the scored portions 44.

16, 19, 21 and 23 consist ofaligned scored portions 45 and perforated portions 46. This type of scoring is employed since the use thereof permits the carton blank to be formed from cardboard material independent of the grain of said material, that is, it is not necessary as heretofore has been the practice, to form the longitudinal scorings in parallel alignment with the grain of the board.

66 The broad idea of a pair of demi-cartons As shown clearly in Fig. 1, the scorings secured in parallel arrangement and side by side so as to be readily detachable is not claimed herein but the features hereinbefore set forth are those which make practical commercial constructions and which are set forth by the claims.
